Acid Resistant and Highly Silver Selective Membranes Based on Charged Nanoporous 2D‐Materials

Small, EarlyView.
In this work, new membranes based on charged & nanoporous nanosheets with unprecedented selectivity to silver versus a wide range of other metallic ions are reported. Furthermore, a demonstrated and lead specific intralamellar lead pathway is demonstrated. A potential applicability for ubiquitous silver in WEEE is validated.

Pulse Electrodeposited NiFeCoMoW High‐Entropy Alloy Electrode for Efficient Alkaline Water Electrolysis

Small, EarlyView.
A pulse‐electrodeposited NiFeCoMoW high‐entropy alloy grown on copper foam forms a binder‐free, hierarchical electrode for alkaline water splitting. The bifunctional catalyst achieves low overpotentials for hydrogen and oxygen evolution and enables efficient two‐electrode electrolysis, delivering 1.52 V at 10 mA cm−2 and 1.83 V at 1000 mA cm−2.

Toward Efficient and Reliable Chemical Upgrading Using Solid Oxide Electrochemical Reactors, Mechanisms, Challenges, and Design Principles

Small, EarlyView.
Solid oxide electrochemical reactors (SOERs) offer a compelling pathway for coupling renewable electricity with chemical manufacturing, but their real application is still limited by low efficiency and instability. This review systematically summarizes SOER reaction mechanisms, performance‐limiting factors, and recent progress toward high‐efficiency ...

The Evolution of Electrochemical and Safety Properties of Nonflammable Triethyl Phosphate Based Electrolyte Under Salt Concentration Control

Safety Science and Technology, EarlyView.
By regulating the lithium salt concentration to alter the solvation structure of Li+, and subsequently affecting the chemical composition of the SEI, the evolution of salt concentration on the electrochemical and safety performance of cells are explored. ABSTRACT Phosphates exhibit excellent flame retardancy. Phosphate‐based electrolytes with high‐salt‐

Accounting for Friendlessness: Stigma and the Quest for an Honorable Self

Symbolic Interaction, EarlyView.
How do people who identify as friendless make sense of their condition in a moment when friendship is extolled for the support and satisfaction it offers? This article draws on interviews with 21 adults in an Atlantic Canadian city. We argue that our interviewees were rarely at ease with their friendlessness and were at pains to recover an honorable ...
